Photography Equipment/Canon and Nikon

Canon and Nikon are the two dominant DSLR makers as of 2007, and have been for a number of years. They are both excellent brands, and both have large followings. That said, they are incompatible (ones lenses don't work on the others body), and in building a collection of equipment, you will choose one or the other. It makes a difference, but not a great one, and after committing to a system, many develop a love-hate relationship with the manufacturer.[1] Some differences are detailed below.

Most importantly, you are choosing a system, not a body. Instead of thinking about minor differences between current bodies, consider which lenses and bodies you expect to be using over the next 10 or 20 years. This is admittedly difficult when starting off, but lenses last decades, and it is prohibitively expensive to switch between systems or have two parallel sets of equipment: switching systems is a major decision.

Ideally, consider what kind of photography you are likely to do or may do for the foreseeable future, and how each system fits it. What equipment would you get initially? Over the next few years? Further down the road?

Also, actually test out both systems: some people fall in love with the Nikon feel, for instance.

Both produce an extensive (which is not to say complete) range of lenses, unlike the other DSLR manufacturers. Both have individual lenses with strong followings; below are notable classes of lenses that they each make.
